Report #52874

[architecture] Multi-agent chain executes an irreversible action based on an early incorrect assumption, wasting compute and requiring costly rollback

Insert human-in-the-loop \(HITL\) approval gates immediately before irreversible state mutations \(e.g., deploying code, executing trades\). Save the full state/context at these gates so execution can resume without recomputation.

Journey Context:
Fully autonomous chains are fast but brittle. A hallucination in step 1 cascades through steps 2-4, and step 5 executes a damaging action. HITL gates act as transaction boundaries. Tradeoff: introducing humans destroys the latency and autonomy of the pipeline. It should only be used for high-stakes, irreversible actions, not routine data transformations. State serialization at the checkpoint is crucial so the human doesn't have to wait for the pipeline to re-run.
